A member asked:
What is the main role of the rectum?
A doctor has provided 1 answer
Rectum and colon: The colon has two main functions. The right half of the colon is where some of the water used in the digestive process is absorbed. The left half is a storage unit for the waste of eating. The rectum is the last portion of the storage area and has slightly more muscle to help propel the waste out during defecation.
